OSA a novel risk factor for sudden cardiac death

In a study of more than 10,000 adults referred for polysomnography who were followed for up to 15 years, 142 patients had fatal or resuscitated sudden cardiac death.

The magnitude of risk of the events was predicted by a range of parameters of OSA severity, including apnoea-hypopnea index >20 and the severity of nocturnal oxygen desaturation, the researchers said.

More clinical trials were needed to investigate OSA therapy in select populations at risk for sudden cardiac death, the
